Channel site — tidal current funnels through here and can run fast, changing quickly with the tide. It is usually strongest around mid-tide and eases near the slack windows below. Dive with a local operator who knows the timing.

About this site

Virgin Blue Hole is a deep cave dive site in Palau's Ngemelis area, known for its long tunnel system and dramatic underwater cave environment.

The site reaches a maximum depth of 32 m, with the defining feature being a deep cave and extended tunnel passage. The terrain is entirely cave-based, requiring divers to navigate through enclosed underwater spaces.

Entry is by boat. The site is best dived at high tide only, which affects conditions inside the cave system. Visibility is generally great, and there is no significant current at this site.

Read the full guide

Virgin Blue Hole is rated as an advanced dive due to the combination of significant depth, confined cave environment, and long tunnel — all of which demand solid buoyancy control and cave-awareness. Sharks are present at the site. Divers without cave or cavern experience should approach with caution.
